Sorry that my earlier lead didn't sort thing out. But unfortunately there is nothing more I can do. Your problem isn't an STD, which is the only expertise this forum has. In my STD clinic, we refer patients like you do gynecologists. Best of luck--
Thank you for your response.
Since posting this I've had two more cultures come back negative for yeast. I don't know what to think because the symptoms haven't gone away and they are still exactly like yeast. I don't know if I should I ignore the tests and try to treat it with some over-the-counter antifungal. I had no luck with that before, but anything is better than sitting here miserable.
Greetings. Welcome to the forum. But I doubt I can help much. When direct examination and testing by a knowledgeable provider doesn't come up with clear answers, it is rare than an online source can do so.
Probably you have a yeast infection; in many ways the microscopic diagnosis by a doctor is is more accurate than culture, which often misses the organism. About 90% of yeast infections are caused by Candida albicans, which is senstive to the imidazole drug class, which includes both Diflucan and Monistat. Most of the rest are caused C. glabrata, which is resistant to the imidazoles and requires alternative treatments, such as nystatin (usually sold generically) or caspofungin (Cancidas). You should discuss this possibility with your doctor.
In the meantime, I see little reason for concern about STDs. The symptoms of yeast are generally quite typical, and STDs typically do not cause the same sort of symptoms. Your negative tests for common STDs also are reassuring.
Avoiding sex until this is sorted out probably makes sense, but mostly just for reasons of comfort. It is unlikely you have anything that could harm your boyfriend, so if sex isn't uncomfortable and doesn't make your symptoms worse, feel free.
